Chris,
I have a Sgt Jenkinson (no initials) in 68 Sqn, with Sgt Kendall as radar operator, claiming an He 111 probable on April 29, 1942. And I have a P/O W Jenkinson in 46 Sqn in the MTO with an unknown radar operator claiming a Z.506 in the "Eastern Mediterranean", date uncertain, possibly August 7, 1943. This from the ORB: Air 27/460. Quite possibly the same person, and maybe more information can be found by going through the 46 Sqn ORB.
